DA Series EMA Advantages Best in Class Lifetime Reliability Diakont DA Series actuators provide superior service life as a result of using robust components such as roller screws (up to 1 times longer than ball-screw). With a greater number of contact points than ballscrew solutions, roller screws provide increased load capacity and rigidity. Diakont design and manufacturing technologies are specially optimized to increase Roller Screw lifetime, due to the optimized geometry of the roller-screws and hardening technology used in the manufacturing process. Diakont offers complete turnkey EMA solutions as well as individual components for your specified needs. Compact Design Diakont EMAs are equipped with inverted roller screws, which require much less space than equivalent ball-screw or hydraulic solutions. This compact design allows end users to easily replace hydraulic or pneumatic actuators with Diakont EMAs. The EMA is also compatible with most servo drives. High Accuracy Diakont DA Series actuators deliver lead accuracy of.25 mm/m (.3 in/ft) along with a nominal backlash of.1 mm (.4 in) - zero backlash options available upon request. The integration of advanced roller screws, which provide significantly higher positioning accuracy over competitor solutions (due to the precisely machined threads), result in high overall accuracy. Easy Maintenance Relubrication is the only maintenance the EMA needs. Diakont EMAs are equipped with easily accessible patented lubrication ports to facilitate scheduled maintenance, without requiring disassembly, recalibration, or removal from the customer s machinery.

Design and Development Diakont offers a broad range of standard actuators to suit most requirements. We also realize that often special application parameters dictate special actuator configurations and modifications. Diakont actuators are designed with this in mind, as many of our products can be readily customized to suit specific requirements. Additionally, Diakont development teams, comprised of mechanical, electrical and application design engineers, handle every aspect of the development process from design to prototype to test and manufacture. Diakont utilizes cutting edge technology for the design and development of electromechanical actuators and subassemblies. Diakont also created a specialized computer-aided design software for performing calculations and modeling planetary-lantern gears, roller screws, and synchronous motors. This advanced program helps development teams design actuators to exact specifications of power, accuracy, and space constraints. 17
